A Decayed Cheerleader is a type of Zombie.
Before getting infected by the unkown virus, this zombie was a young woman who got to be a cheerleader because of her beauty. Of course, her beauty ended when her flesh started to rot as her corpse was already wandering aimlessly to find more fresh meat to eat. If this zombie's corpse is looted you might find Water Bottle, Paper, Stick, Cloth Fragment &/or Glass Jar.
One headshot with a 100% condition Pistol is enough to kill it on difficulties below insane. It's easy to strike a headshot on this zombie because of her movement, so using a Crossbow is recommended.
During night, the running behaviour is standard as all other zombies. If distance or sheer zombie numbers aren't a concern, scoring a headshot when it's running headfirst towards you can be slightly easier.
As of Alpha 10, decayed cheerleaders are slightly weaker than other zombies (3 100% condition non-crit headshots from a spiked club will drop them on insane vs 4 for standard zombies), but notably faster in both walking and running speed. When sniping a pack from an insecure location (e.g., the ground, while being chased), these should probably be second priority after dogs.
